HEEL-TRlMM lNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 280,717, dated July 3, 1883.

Application filed April 23, was. (No model.)

To all whom it may concern:

having its periphery curved longitudinally tocorrespond substantially to the desired vertical curveto be given to the heel-edge is used; and it consists in certain novel combinations and arrangements of parts, which will be best understood by reference to-the description of the drawings and to the claims to be hereinafter given.

Figure 1 of the drawings is a side elevation of amachine embodying my invention. Fig. 2 is an end elevation of the same, and Fig. 3 is a longitudinal section through the cutter and tread and rand guides or gages.

Ais the frame of the head, provided with the flange A, by which it may be secured to a suitable column, bench, or other support, and having mounted in the bearings A A the shaft B, upon which are secured the driving pulley C, the hand-wheel D, and the cutter E,

=all constructed and arranged in a well-known manner. The cutter E has secured to one end thereof, so as to revolve therewith, the treadsurface gage F, and to its other end the randguide G, The gage F is made considerably larger in diameter than the greatest diameter of the cutter E, and has its outer portion beveled, as shown, to permit the trimming of heels, the upright sides of which form greater or less angles to their tread-surfaces. The rand-guide G has its outer cornenbeveled, so as to reduce its thickness at its outer edge, so that it may enter between'the upper and the sole, and thus guide the boot or shoe in its movement as it is rotated, in order to present the sides and rear end of the heel to the action of the cutter.

while it is being presented to the action of the cutter. The axis upon which the wheel H is mounted is set in or formed upon the end of the horizontal arm of the knee-shaped rod or bar I, mounted by its vertical arm in a socket formed in one end of the rod J, which in turn is adjustably secured in the ear K on the frame A by means of the set-screw a, as shown in Figs. 1 and 2. The knee-shaped rod I is secured in the socket of the rod J by the setscrew 1), so that it may be adjusted vertically, and also about the axis of its'vertical portion, while at the Same time the rod J may be ad justed endwise in the ear K, and turned about its axis, by virtue of which combined adj ustments the wheel H may be set in any required position relative to the cutter E.

The wheel-rest is an improvement upon a I fixed or non-rotating rest, because of the greater ease of manipulating the boot or shoe; but it is absolutely essential to its successful operation that it shall be mounted upon an inclined axis, for the reason that unless it is so mounted the boot or shoe cannot be placed in the proper position at the commencement of the trimming when the breast of the heel has to be placed upon the rest, as in many boots and shoes the spring of the shank is so great, or the angle of the shank is such relative to the tread-surface of the heel, that the wheel-rest, if mounted upon a horizontal axis, would interfere therewith and prevent the boot or shoe heel from being placed in the proper position thereon.

The operation of my invention is as follows:

, The parts being properly adjusted to the particular job in hand, and power being applied to the pulley G to revolve the shaft B and cutter E at a high rate of speed, the breast of the boot or shoe heel is placed upon the upper edge of the wheel-rest H, with its tread-surface bearing against the gage F, and the boot or shoe is revolved till the whole of the sides and rear portion of the heel-edge has been acted upon by the cutter and trimmed to the desired shape, except that the heel-seat is left 9 5 somewhat full. The boot or shoe is then placed with its breast upon the wheel-rest, as before, but in such a position that the rand-guide G enters the crease between the upper and the upper surface of the sole, or heelseat,

IOO

so called, and the boot or shoe is again rcvolved to bring all parts of the heel-seat into contact with the cutter, and thus retriin the same without changing the shape of the treadsurface of the heel.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In combination with a rotary cutter adapted to trim the edges of boot or shoe heels, the wheel-rest H, made in the form of a frustum of a cone, and mounted upon an inclined axis, and arranged and adapted to support the boot or shoe heel upon its edge, substantially as described.

2. In a hceLtrinnning maehine,the combination of cutter E, the wheel'rest H, made in the form of the frustuln of a cone, and the adjustable rods I and J, all constructed, arranged, and adapted to operate substantially as and for the purposes described.

3. The combination of the cutter E, the tread-surface gage F, the randguide G, and the frusto-conical wheel-rest H, all constructed, arranged, and adapted to operate substantially as and for the purposes described.

In testimony whereof I have signed my name to this specification, in the presence of two sub scribing witnesses, on this 19th day of April, A. D. 1883.
